Abstract

Process for the calibration or mechanical adjustment or calculation of a drive current, especially a break-induced current, of a solenoid-powered actuator for regulating the differential pressure-dependent flow of a liquid comprises determining the extent of the pressure effect generated by the actuator in advance using the strength of the electrical drive current without the use of pressure sensors. One or more actuator-specific calibration curves, characteristics or constants for the actuator are derived so that a set flow (G) can be specifically achieved using the constants by adjustment with the strength of the current. The actuator-specific constants can be automatically determined without pressure loading the actuator. Independent claims are also included for: (1) Actuator; (2) Process for adjusting the opening position of and/or flow through a solenoid-powered actuator; and (3) Process for measuring the pressure of a fluid using a solenoid-powered actuator without additional pressure sensors.
